Anyone else having a problem with this? I have what I thought was a straightforward piece of code...
If InpEng.IsKeyPressed(MTV3D65.CONST_TV_KEY.TV_KEY_0) Then
Physics.SetBodyLinearVelocity(dTank.pBodyId, New TV_3DVECTOR(0, 0, 2))
End If
What I thought this would do was move my object at a constant velocity of 2 along the Z axis, provided I was pressing the 0 key.
Well, it works for a little bit...and then I get this error, after like 2-3 seconds.
TestApp.vshost.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Any ideas?

This sounds quite strange, try setting Physics.SetThreadCount(1) maybe there is some multithreading problem.

Lol, that wasn't good...when I set it to 1 (it was set to 4), I get "Attempted to read or write protected memory" on Physics.SimulateFixedStep(TimeElapsed * 0.003, 0.3).
I set it to 2 instead and the previous error happened again.
I swear, every time I start to think I'm getting a grip on Physics and can actually start to use it for something, seems like one bizzare thing after another pops up!

Now that's intereseting...I commented out these lines...
Physics.SetThreadCount(4)
Physics.SetMaxEventCount(256)
And now it seems to work fine. Can anyone explain that?

I know there was a bug in the physics engine that would cause these types of errors, but I think Sylvain already fixed it some time ago, are you using the newest version of the engine? Maybe there are still some threading problems left after all.

Yes, I know I'm using the latest version of the engine, just downloaded it like 3 days ago.

As usual, if you could post here a small demo of this problem, that will help me to fix the bug.

i'll see if I can re-create it in a smaller project Syl, its tied up a huge amount of spaghetti code right now.
